This article in studies on the SCOOT and SCATS system's merits and demerits, according to our urban road network system's characteristics, has designed one system based on the closed ring circuit auto-adapted region transportation coordination control.

研究SCOOT系统和SCATS系统性能优缺点，根据我国城市道路网系统的结构特点，设计了一种基于闭合环路的自适应区域控制系统。

Through analyzing report forms format of IEC 60 870-5104 stipulation,as well as considering computer monitoring system of 330kV Dashimen and Jingyang substation and experiences of provincial dispatching system,the paper studies some command flow,and provides technical safeguard for provincial dispatching automation system adopting network stipulations transmission process.

通过分析IEC 60 870-5-104规约的报文格式，借鉴330 kV景阳变、大石门变计算机监控系统和省调自动化系统的联调经验，研究了规约的各种命令流程，为省调自动化系统采用网络规约传输提供了技术保障，同时也极大地丰富了调度自动化系统的应用范围。

In this paper, we mainly study the system performance and key technologies of satellite optical CDMA communication system.

给出了卫星二维光CDMA通信系统方案和系统模型，并分析了该通信系统的系统性能。

The four major Dao bodies are complementary in function, and their relationship is that associations operate on the basis of the information and logistic systems, information and logistic systems provide the functional conditions for the natural operation of associations, and the awakening culture provides the intelligent conditions for the natural operation of associations.

四大道体具有功能互补的性质，相互之间的关系是：协会组织在信流系统和物流系统的基础上运行，信流系统和物流系统为协会组织提供自然运行的功能条件，觉醒文化为协会组织提供自然运行的智能条件。

Because the information in groupware system has Characteristic of complex, various, large quantity, non-structure or structure complex, close relativity of information, etc, and the traditional relational database can hardly handle these complex and various information. This paper aims at the problems that groupware system meets in application, put forward the research on groupware system based on object-oriented database management system.

由于群件系统中所处理的信息具有复杂、多样、量大、非结构化或结构复杂以及信息间的相关性紧密等特征，而传统的关系型数据库很难处理这些复杂多样的信息，因此，本文针对群件系统对数据库的应用需求，提出了基于面向对象数据库管理系统的群件系统的研究。

The coordinated development is the final goal of Energy-Economy-Environment system because of the complicatedly interdependent and interactional relationships among them.

能源系统与经济系统、环境系统存在着相互影响、相互制约的发展关系，三者的协调发展是3E系统发展的最终目标。

A secure system consists of many sub——systems, even though every one of those sub-systems satisfies a certain security property, the composed system may not be secure, i.e. the composition maybe not satisfy the security property. It does mean that the security property should be composable.

安全系统是由许多子系统组成，每一子系统都必须满足一定的安全性质，但这不能保证由这些子系统组合而成的系统也是安全的，即组合的系统不一定也满足给定的安全性质，所以要求系统的安全性质满足可结合性。

A conditional probability density function of the SAR imaging systems is derived, These works lay a foundation for further research.

将SAR成象系统视为一个多元接入信息系统，在深入分析系统构成的条件下，求出该系统的传递概率密度函数。

Then the stationary joint probability density, the conditional reliability function, the mean first-passage time of the optimally controlled system are obtained from solving the reduced FPK equation, the backward Kolmogorov equation and the Pontryagin equation, respectively of fully averaged systems.

求解与之相应的Fokker-Planck-Kolmogorov方程得最优控制系统的联合概率密度，进而求得最优控制系统的平均幅值；求解与之相应的后向Kolmogorov方程得最优控制系统的条件可靠性函数，进而求得首次穿越时间的条件概率密度；求解与之相应的Pontryagin方程得最优控制系统的平均首次穿越时间。

From a practicable point of view, models in MBMS were further classified into three types: Mathematical Equation Model, Conditional Model, and Image Processing Model.

本文着重研究基于地理信息系统的模型库管理系统，试图通过建立模型库管理系统的方法弥补地理信息系统在模型分析方面的不足。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.
